Insight into Sulfur Reactions in Li–S Batteries

ACS Applied Materials & Interfaces, 2014
Understanding and controlling the sulfur reduction species (Li2Sx, 1 ≤ x ≤ 8) under realistic battery conditions are essential for the development of advanced practical Li-S cells that can reach their full theoretical capacity. However, it has been a great challenge to probe the sulfur reduction intermediates and products because of the lack of methods.

In Situ Techniques for Developing Robust Li–S Batteries [PDF]

Small Methods, 2018
AbstractRechargeable lithium–sulfur batteries (LSBs) are of great interest in the field of energy storage due to their favorable operational characteristics, for example, high theoretical energy density and low cost. However, LSBs are limited by long‐term degradation, caused by the dissolution of intermediate lithium polysulfide phases.

The Role of Metal Disulfide Interlayer in Li–S Batteries

The Journal of Physical Chemistry C, 2017
Recently many observations related to the catalytic effects of layered metal disulfide versus polysulfide electrochemistry were documented. In this work, we investigated the reactivity of layered WS2 in a Li-S battery and observed a chemical reaction involving the removal of W ions by polysulfides. The presence of metallic tungsten nanoparticles in the

Li–S batteries: Firing for compactness

Nature Energy, 2017
Conventional Li–S batteries have a non-compact cathode structure containing low areal loading of active materials. Now, a strategy of burning Li foils in a CS2 vapour is presented, which leads to the formation of highly compact Li2S nanoparticles as a lithiated sulfur cathode, offering promising battery performance.
